Jump to Iden.y-based encryption algorithms - ID-based encryption, or iden.y-based encryption IBE , is an important primitive of ID-based cryptography. As such it is a type of public-key encryption in which the public key of a user is some unique information about the iden.y of the user e.g. a user 's email address ..HPE Iden.y-Based Encryption IBE takes a breakthrough approach to the problem of encryption key management. HPE IBE can use any arbitrary string as a public key, enabling data to be protected without the need for certificates. The stateless nature of HPE IBE also dramati.y . - An Iden.y Base Encryption IBE scheme is a public-key cryptosystem where any string is a valid public key. In particular, email addresses and dates can be public keys. The IBE email system is based on the first practical Iden.y-Based Encryption scheme IBE ..Iden.y Based Encryption IBE solves this problem by allowing some identifier string e.g. an e-mail address to be used as public key, thus eliminating the prior .
